I just bought a 1988 Ranger 390 from the original owner (he's 80!). It has the original 1988 Johnson GT 150 on it. He told me that after a couple years he had heard of motors blowing due to the VRO system failing, so he has mixed oil in the gas at 50 to 1 ever since.

I have owned various OMC motors from 70 hp to 115 hp in the late 80's and early 90's that all had VRO and never had a problem.

Does anyone have input on this subject? If the system is good, and I hook it back up, any downside? Is this a case of letting a sleeping dog lay and just continue mixing the oil with the gas?

Any input appreciated.

(Yes, it would be nice to buy a new 200 hp, but not in the budget this year!)
